Sulphur Brown 1 Usage And Synthesis
Preparation
lignite and Sodium polysulfide and sulfur in the rolling roasting reactor heating (BIOS983, 44) 0 organic waste and sulfur and Sodium sulfide in 100 ~ 350 ℃ under different temperature heating, the higher the temperature, reaction product color is dark. lignite, sawdust, chaff bran, Cellulose microcrystalline liquid waste (decalcified), oil, fat and fatty acid kit, etc. Can be used as the alternative intermediates.
Properties and Applications
brown light olive to yellow brown. Dark brown powder. Soluble in water for green black or brown, long time after boiling insoluble. In concentrated sulfuric acid for brown, there are hydrogen sulfide gas evolution, dilution after brown precipitation; In the Sodium hydroxide solution for the green.
